Trans-Tasman Emissions Trading Scheme Challenge: Part Two

With the passage of the Australian “Clean Energy Future” legislation, Simon Johnson (aka Mr February) makes another trans-tasman emissions trading scheme comparison.

Yesterday the Australian Parliament adopted legislation for its greenhouse gas emissions trading scheme. It’s time, therefore, for another post on the theme of the “Trans-Tasman Emissions Trading Scheme test series”, looking at the key differences between the New Zealand Emissions Trading Scheme and the Australian Emissions Trading Scheme. The number one key difference between the two emissions trading schemes is in how clearly each scheme sets the carbon price.

We have the technology, but…

“One word sums up the attitude of engineers towards climate change: frustration.” That’s Colin Brown, director of engineering at the UK’s Institution of Mechanical Engineers, writing in the latest New Scientist. Political inertia combines with continuing noise from the vocal minority of sceptics to mean that we are doing woefully little to prevent the worsening of global warming.

It’s not as if we are lacking the technology:

Engineers know there is so much more that we could do. While the world’s politicians have been locked in predominantly fruitless talks, engineers have been developing the technologies we need to bring down emissions and help create a more stable future.

Wind, wave and solar power, zero-emissions transport, low-carbon buildings and energy-efficiency technologies have all been shown feasible. To be rolled out on a global scale, they are just waiting for the political will. Various models, such as the European Climate Foundation’s Roadmap 2050, show that implementing these existing technologies would bring about an 85 per cent drop in carbon emissions by 2050. The idea that we need silver-bullet technologies to be developed before the green technology revolution can happen is a myth. The revolution is waiting to begin.

The barriers to a low-carbon society are not technological but political and financial, he declares. That’s why at a London conference this month 11 national engineering institutions representing 1.2 million engineers from across the globe decided on a joint call for action to be presented at December’s COP17 climate change conference in Durban, South Africa.

New Opencast Mine Permitted

News today that resource consent has been granted to Perth-based company Bathurst Resources for opencast coal mining on 200 hectares in the Mt Rochfort Conservation Area on Denniston Plateau, northeast of Westport. It will become New Zealand’s second largest opencast coal mine after Solid Energy’s nearby Stockton mine.

The commissioners said that the consent was granted “not without some considerable reservations and anguish” and that they “do not wish to provide any indication that future consents will be granted to undertake further mining in this area.” But the economic benefits easily carried the day:

“The most and almost overwhelming factor that we had to consider is the enormous financial benefit that the mine will bring to the Buller district and the West Coast region.” Continue reading “New Opencast Mine Permitted”

The Climate Show #12: twisters, Olaf on ozone, and Google in the sun

Ozone is the centrepiece of our show this week, with Dr Olaf Morgenstern of NIWA’s Central Otago atmospheric science lab (celebrating its 50th birthday at the moment) explaining the ins and outs of the ozone holes north and south, and their impacts on the climate system. Plus tornadoes, heatwaves, UN negotiations at an impasse, more melting in the Arctic, airships, see-through solar cells and Google’s solar towers. No John Cook this time — he’s been too busy launching his book (good luck with that John!).

Return of the Climate Clueless™: there’s none so blind…

Sir Peter Gluckman, scientific adviser to NZ prime minister John Key, recently published a discussion paper entitled Towards better use of evidence in policy formation (pdf). It’s an interesting read for anyone who has ever noted the sometimes large discrepancy between political dogma and policy outcomes. Sciblogger Peter Griffin went so far as to describe it as “possibly one of the most important [papers] he has released thus far”.

Over in the land of the Climate Clueless™ however, Richard “Climate Conversation” Treadgold has taken Gluckman’s paper as a cue to demand evidence of climate change. Treadgold appears to have forgotten that one of Sir Peter’s first acts following his appointment was to review the evidence and issue a statement on the subject, and is perhaps still smarting from Gluckman’s comments on climate denial last year. He therefore issues this stern challenge:

I would remind Sir Peter that evidence is required to establish the following key factors in the global warming debate — evidence that has not surfaced so far. We have been looking for evidence to show:

  1. The existence of a current unprecedented global warming trend.
  2. That the greenhouse effect is powerful enough to endanger the environment.
  3. A causal link between human activities and dangerously high global temperatures.
  4. That climate models have a high level of skill in predicting the climate.
  5. A causal link between atmospheric levels of carbon dioxide and global temperatures.
  6. A causal link between global warming and the gentle rise in sea level.

Time to play some whack-a-mole…
